# Smart Health System for Plants

# Problem

There are many families in this world that - for a variety of reasons - are away from home and have plants sitting at home waiting for them to come back and provide water and sunlight. Further, many families love to have plants but don't have time to watch over them due to jobs and busy schedules. In these times, many plants can die out causing the owners to either purchase a new plant or throw out the old one completely. This is not only a problem of neglect, but also sustainability on a broader scope.

# Solution

To solve this problem and have plant owners save money by not having to buy new plants, we would create a Smart Health System for Plants with a Phone UI for the owner. We would create a plant potter which is built in with our Smart Health System and provides connectivity to the owner through a UI. In our system, we would use different sensors to measure values like humidity, soil moisture and sunlight provided to determine exactly how much water/sunlight the plant will need. We then pump in water from our water reservoir straight to the roots and provide light when needed. Further, through the UI, the owner would also be able to provide manual water and artificial light when they want to and see critical values from the sensor module. Overall, this Smart Health System for Plants will provide plants with the most ideal conditions they need to grow and survive and owners will never have to worry about dead plants due to their busy schedules and family vacations. Further, this system will consist of a sensor module, microcontroller, watering system, artificial sunlight system and a phone UI.

# Solution Components

## Sensor Module

In this system, we would use the sensors listed below to provide values to our microcontroller to be used in our algorithm to determine when the plant will need water and light. These sensor values will also be reflected in our Phone UI where the owner will be able to see all the critical values around their plant.

- Soil Moisture Sensor (Waveshare Moisture Detection Sensor Module)-https://electropeak.com/waveshare-moisture-sensor
- Humidity and Temperature Sensor (DHT22 Temperature Sensor)-https://www.sparkfun.com/products/18364
- Light Sensor (Grove-Sunlight Sensor or Photoresistor)-https://wiki.seeedstudio.com/Grove-Sunlight_Sensor/

## Microcontroller

In this system, we will connect all of our sensors, watering system, artificial light system and phone UI to control different parts of our Smart System. We will take values from our sensors and turn on/off the watering system and artificial light system. Further, we will also use the commands from the Phone UI to control the watering system and light system.

## Watering System

In this system, we will use a water reservoir which will be controlled by a pump connected to our microcontroller. When we determine the plant needs water, we will run the pump for a specific amount of time which will be determined by our algorithm and controlled by our Arduino microcontroller. We will also use a water level sensor to notify the owner when the water is running low and needs a refill

## Artificial Light Module

In this system, we will connect an overhead light system to help provide light to the plant when our algorithm determines the plant needs some light. We will connect this module to our microcontroller to help control turn on and off the light when we need to. This can also be controlled by our Phone UI on a manual basics when the owner needs it

## Phone UI

In this system, we will create a UI for the owner which will interact with our microcontroller and provide graphs for the sensor values and ability to water the plant manually. We will also provide a way the owner can select their plant from our created plant library or create their own plant and enter specific values we need to make sure their plant gets enough water to stay healthy and survive.

- Software Code

# Criterion For Success

With the time given to us in ECE445 to complete this project, we want to be able to see our watering system run automatically using the sensor values and the microcontroller. Further, we at least want to see our Phone UI be able to provide water to the plants on a manual basis. Further, at minimum we want our system to have a few coded algorithms for plants which can be run on its own to water the plants automatically.

- Automatically use sensor values and provide water/sunlight throughout the day
- Use the phone UI to see sensor values and manually provide the plant water
- Use the phone UI manually provide the plant artificial sunlight

# Problem

Buses are scheduled inefficiently. Traditionally buses are scheduled in 10-30 minute intervals with no regard the the actual load of people at any given stop at a given time. This results in some buses being packed, and others empty.

# Solution Overview

Introducing the _BusPlan_: A network of smart detectors that actively survey the amount of people waiting at a bus stop to determine the ideal amount of buses at any given time and location.

To technically achieve this, the device will use a wifi chip to listen for probe requests from nearby wifi-devices (we assume to be closely correlated with the number of people). It will use a radio chip to mesh network with other nearby devices at other bus stops. For power the device will use a solar cell and Li-Ion battery.

With the existing mesh network, we also are considering hosting wifi at each deployed location. This might include media, advertisements, localized wifi (restricted to bus stops), weather forecasts, and much more.

# Solution Components

## Wifi Chip

- esp8266 to wake periodically and listen for wifi probe requests.

## Radio chip

- NRF24L01 chip to connect to nearby devices and send/receive data.

## Microcontroller

- Microcontroller (Atmel atmega328) to control the RF chip and the wifi chip. It also manages the caching and sending of data. After further research we may not need this microcontroller. We will attempt to use just the ens86606 chip and if we cannot successfully use the SPI interface, we will use the atmega as a middleman.

## Power Subsystem

- Solar panel that will convert solar power to electrical power

- Power regulator chip in charge of taking the power from the solar panel and charging a small battery with it

- Small Li-Ion battery to act as a buffer for shady moments and rainy days

## Software and Server

- Backend api to receive and store data in mongodb or mysql database

- Data visualization frontend

- Machine learning predictions (using LSTM model)

# Criteria for Success

- Successfully collect an accurate measurement of number of people at bus stops

- Use data to determine optimized bus deployment schedules.

- Use data to provide useful visualizations.

# Ethics and Safety

It is important to take into consideration the privacy aspect of users when collecting unique device tokens. We will make sure to follow the existing ethics guidelines established by IEEE and ACM.

There are several potential issues that might arise under very specific conditions: High temperature and harsh environment factors may make the Li-Ion batteries explode. Rainy or moist environments may lead to short-circuiting of the device.

We plan to address all these issues upon our project proposal.

Accuware currently has a device that helps locate wifi devices. However our devices will be tailored for bus stops and the data will be formatted in a the most productive ways from the perspective of bus companies.
